Tony Nguyen says: ==================== ice: implement SRIOV VF Active-Active LAG Dave Ertman says: Implement support for SRIOV VFs over an Active-Active link aggregate. The same restrictions apply as are in place for the support of Active-Backup bonds. - the two interfaces must be on the same NIC - the FW LLDP engine needs to be disabled - the DDP package that supports VF LAG must be loaded on device - the two interfaces must have the same QoS config - only the first interface added to the bond will have VF support - the interface with VFs must be in switchdev mode With the additional requirement of - the version of the FW on the NIC needs to have VF Active/Active support The balancing of traffic between the two interfaces is done on a queue basis. Taking the queues allocated to all of the VFs as a whole, one half of them will be distributed to each interface. When a link goes down, then the queues allocated to the down interface will migrate to the active port. When the down port comes back up, then the same queues as were originally assigned there will be moved back. Patch 1 cleans up void pointer casts Patch 2 utilizes bool over u8 when appropriate Patch 3 adds a driver prefix to a LAG define Patch 4 pre-move a function to reduce delta in implementation patch Patch 5 cleanup variable initialization in declaration block Patch 6 cleanup capability parsing for LAG feature Patch 7 is the implementation of the new functionality * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: Implement support for SRIOV VFs across Active/Active bonds ice: cleanup capabilities evaluation ice: Cleanup variable initialization in LAG code ice: move LAG function in code to prepare for Active-Active ice: Add driver specific prefix to LAG defines ice: replace u8 elements with bool where appropriate ice: Remove casts on void pointers in LAG code ==================== Link: https://patch.msgid.link/20250814230855.128068-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
